input
- the string to be parsed (should not be null)nodes
- vector containing GraphNode objects (should be empty)edges
- vector containing GraphEdge objects (should be empty)

parse
public java.lang.String parse() throws java.lang.Exception
This method parses the string or the InputStream that we passed in through the constructor and builds up the m_nodes and m_edges vectors- Returns:
- returns the name of the graph
- Throws:
java.lang.Exception
- if both the inString and inStream are null, i.e. no input has been providedBIFFormatException
- if there is format of the input is not correct. The format should conform to XMLBIF version 0.3java.lang.NumberFormatException
- if there is an invalid char in the probability table of a node.
-
writeXMLBIF03
public static void writeXMLBIF03(java.lang.String filename, java.lang.String graphName, FastVector nodes, FastVector edges)
This method writes a graph in XMLBIF ver. 0.3 format to a file. However, if is reloaded in GraphVisualizer we would need to layout the graph again to display it correctly.- Parameters:
filename
- The name of the file to write in. (will overwrite)graphName
- The name of the graph. (will be the name of network tag in XMLBIF)nodes
- Vector containing all the nodesedges
- Vector containing all the edges
